[Supras] 88 Auto Trans

[Dave Henry]

You can try a fluid with friction modifiers in it.  We use Case IH Hy-Tran 
in our race powerglides.  It has a strong friction modifier and really firms 
up the shifts.  This might solve your problem (at least temporarily) if it's 
actually a clutch slippage problem.
